Nice antique piece of Los Angeles California history. Unused 1903 2c postal stationary envelope.  Typewritten: Owens River Campaign Committee, Chamber of Commerce, Los Angeles. Shows age-appropriate discoloration, and a mark down the center, but no folds. Please see photos for your visual inspection.
